  • Three experiments were conducted to evaluate the ME value, standardized ileal digestibility (SID) of amino acids (AA) of fish meal, and the effects of single cell protein (Prosin and Protide) replacing fish meal in diet on growth performance, nutrient digestibility and intestinal morphology in weaned piglets. In Exp. 1, twenty-four barrows with initial BW of $30.8{\times}2.6kg$ were allotted to one of four dietary treatments. Diet 1 contained corn as the only energy source. The other three diets replaced 20% of the corn in diet 1 with one of the three protein feeds (fish meal, Prosin and Protide), and the DE and ME contents were determined by difference. In Exp. 2, eight barrows (initial BW of $25.6{\pm}3.2kg$) were fitted with ileal T-cannulas and allotted to a replicated $4{\times}4$ Latin square design. Three cornstarch-based diets were formulated using each of the protein feeds as the sole source of AA. A nitrogen-free diet was also formulated to measure endogenous losses of AA. In Exp. 3, one hundred and eighty piglets (initial BW of $7.95{\pm}1.59kg$) weaned at $28{\times}2d$ were blocked by weight and assigned to one of five treatments for a 28-d growth performance study, each treatment was fed to six pens with six pigs (three barrows and three gilts) per pen. The five treatments consisted of the control group (CON), which was a corn-soybean meal diet containing 5% fish meal, and the other four treatments, which replaced a set amount of fish meal with either Prosin (2.5% or 5%) or Protide (2.5% or 5%). The diets were formulated to provide same nutrient levels. The results showed that on a DM basis, both of the DE and ME contents were lower in Prosin and Protide than that of fish meal (p<0.05). The SID of CP and all essential AA were greater in fish meal than in Prosin and Protide (p<0.05). The pigs fed CON diet had greater weight gain and lower feed conversion rate (FCR) than pigs fed 5% Prosin and 5% Protide diets (p<0.05). The digestibility of CP was greater in pigs fed CON, 2.5% Prosin and 2.5% Protide diets than the pigs fed 5% Prosin and 5% Protide diets (p<0.05). Villus height in jejunum and ileum, and villus height to crypt depth ratio in the jejunum were higher (p<0.05) in pigs fed CON, 2.5% Prosin and 2.5% Protide diets compared with the 5% Prosin and 5% Protide diets. Pigs fed CON diet had greater villus height to crypt depth ratio in the ileum than the pigs fed 5% Prosin and 5% Protide diets (p<0.05). In conclusion, although Prosin and Protide contained lower ME content and SID of AA than fish meal, Prosin and Protide replacing 50% of fish meal in diet with identical nutrient levels could obtain similar performance, nutrient digestibility and intestinal morphology in weaned pigs.

  • The case management has been applied to improve the quality of care and the cost-effectiveness in the most health care institutions. In a way of case management, the critical pathway(CP) has been executed in many acute care settings, focused on the diagnoses with high cost, high volume, and high risk. This study was conducted to develop a case management program using CP as an intervention of patients with lumbar spinal stenosis for the surgery of posterolateral fusion, and to find out the effects of the critical pathway on the quality of nursing care, patient satisfaction as an outcome of care, length of stay and medical charge, and nurses' job satisfaction. At the same time, patients' functional states were checked with the Oswestry Low Back Pain Index, to show that the CP would not decrease the patients' function compared to the control group. The subjects were 25 control patients with a usual operation of lumbar fusion and 25 experimental patients with CP. They were all female, aged $50s{\sim}70s$, admitted in the Orthopedic surgery ward of a university hospital. Also nurses on the floor using CP were asked to respond to measurement tool of job satisfaction before and after the application of CP, and compared with other nurses on the different wards. Data were analyzed with t-test for continuous variables and chi-square for non-parametric variables in addition to the reliability test of the measurement tools. The results of this study were as followings: 1. Patients' functional states The differences in Oswestry scores of the experimental and control groups assessed at preoperation and at discharge were not statistically significant. The change in scores of the experimental group measured at preoperation and at discharge was larger than that of the control group, however the difference was not statistically significant. The results indicate that the CP did not decrease the patients' functional status. 2. The quality of nursing care The total of quality of nursing care given to the experimental group was better than that of the control group(P=.000). In addition, the experimental group showed better scores of quality of every item of care than the control group(P=.000 -.004). 3. Patient satisfaction Patients of the experimental group were not more satisfied with general care than the control group. But they were more satisfied with discharge care of 'explanation about medication, body posture, and brace application' and 'explanation about the adjustment of daily living and exercise during recovery'(P= .047, P=.028). 4. Nurses' job satisfaction Nurses working with the CP showed more job satisfaction than before the CP introduction(P=.048). But the control group of nurses on a different floor showed no change in job satisfaction at the same period of time. 5. Length of stay and medical charge The mean length of stay of the experimental group was shorter than that of the control group without statistical significance. The charge of medication and treatment of the experimental group were smaller than that of the control group(P=.011, P=.000). The results of the study support that the case management using critical pathway enables to improve the quality of care and job satisfaction, to reduce the medical charge, and consequently to increase satisfaction with care. However, the case management should be instituted focusing on the quality improvement of nursing and the client satisfaction, not just for the purpose of cost-effectiveness of health care facilities.

  • A dramatic development in the new technology of copying materials has presented us with massive problems on reconciling the conflicts between copyright owners and potential users of copyrighted materials. The adaptation to this changing condition led some countries to revise their copyright laws such as in the U. S. in 1976 and in Korea in 1984 for merging with the international or universal copyright conventions in the future. Copyright defined as exclusive rights given to copyright owners aims to secure a fair return for an author's creative labor and to stimulate artistic creativity for the general public good. The exclusive rights on copyrightable matters, generally for reproduction, preparation of derivative works, public distribution, public performance, and public display, are limited by fair use for scholarship and criticism and by library reproduction for its preservation and interlibrary loan. These limitations on the exclusive rights are concerned with all aspects of library services and cause a great burden on librarian's daily duty to provide balance between the rights of creators and the needs of library patrons. The fair use as one of the limitations on it has been coupled with enormous growth of a new technology and extended from xerography to online database systems. The implementation of the fair use and library reprography in Korean law to the local practices is examined on the basis of the new American copyright act of 1976. Under the draft revision of Korean law, librarians will face many potential problems as summarized below. 1. Because the new provision of 'life time plus 50 years' will tie up substantial bodies of material longer than the old law, until that date librarians would need permissions from the owners and should pay attention to the author's death date. 2. Because the copyright can be sold, distributed, given to the heirs, donated, as a whole or a part, librarians should chase down the heirs and other second owners. In case of a derivative work, this is a real problem. 3. Since a work has its protection from the moment of its creation, the coverage of copyrightable matter would be extended to the published or the unpublished works and librarian's work load would be heavier. Without copyright registration, no one can be certain that a work is in the public domain. Therefore, librarians will need to check with an authority. 4. For implementation of limitations on exclusive rights, fair use and library reproduction for interlibrary loan, there can be no substantial aggregate use and there can be no systematic distribution of multicopies. Therefore, librarians should not substitute reproductions for subscriptions or purchases. 5. For the interlibrary loan by photocopying, librarians should understand the procedure of royalty payment. 6. Compulsory licenses should be understood by librarians. 7. Because the draft revision of Korean law is a reciprocal treaty, librarians should take care of other countries' copyright law to protect foreign authors from Korean law. In order to solve the above problems, some suggestions are presented below. 1. That copyright clearinghouse or central agency as a centralized royalty payment mechanism be established. 2. That the Korean Library Association establish a committee on copyright. 3. That the Korean Library Association propose guidelines for each occasion, e.g. for interlibrary loan, books and periodicals and music, etc. 4. That the Korean government establish a copyright office or an official organization for copyright control other than the copyright committee already organized by the government. 5. That the Korean Library Association establish educational programs on copyright for librarians through seminars or articles written in its magazines. 6. That individual libraries provide librarian's copyright kits. 7. That school libraries distribute subject bibliographies on copyright law to teachers. However, librarians should keep in mind that limitations on exclusive rights are not for an exemption from library reprography but as a convenient access to library resources.

  • 근위 상완골 골절은 골절의 형태에 따라 크게 관절편 또는 해부학적 경부, 대 결절, 소 결절, 상완골 간부 또는 외과적 경부의 4개의 골절편으로 나눌 수 있다. 현재 널리 사용되고 있는 Neer의 근위 상완골 골절의 분류는 골절선에 의해 골절편을 나누는 분류가 아니며, 1 cm이상전이나 45$^{\circ}$ 이상의 각형성 이 있는 경 우를 전 이 골절편으로 생각하였다. 골절에 대한 관혈적 정 복 및 내고정술의 일차적 적응증은 골다공증이 없는 젊은 환자에서 발생된 튼튼한 내고정물을 시행할 수 있는 삼분 골절로 만족할 만한 결과를 위해 술후 오랜 기간동안 시행할 재활치료에 잘견딜수 있는 활동력 이 좋은 환자여야 한다. 수술적 치료의 절대적 적응증은 개방성 골절 ,혈관이 나 신경 손상이 동반될 때 , 정복이 불가능한 골절 탈구등이다. 반대로 환자가 골다공증이 심하거나, 근위 상완 골절편의 분쇄정도가 심하며 , 튼튼한 내고정을 시행할 가능성 이 희박한 나이가 많은 경 우에는 관혈적 정복 및 내고정술보다 일차적 인공삽입물을 이 용한 관절성형 술을 시행한 후 조기 재활 치료를 시행하는 것을 고려할 수 있다. 상완골 근위부 골절의 수술적 요법에는 다양한 수술 기법과 이에 따른 여러 합병증이 발생할 수 있으며 지속적 이고 체계적 인 재활 치 료가 꼭 필요하다. 여러 수술 기 법 중 관혈적 정복 및 장력 대 강선 기법을 시행할 때 만족할 만한 결과를 얻 을 수 있다. 이 방법 은 수술적 기법이 어렵지 않고, 골에 대한 고정과 함께 회전근 개의 건부착 부위에 대한 봉합을 추가할 수 있으나 역시 여러 가지 합병증이 있으므로 골절의 양상이 나 환자의 상태 ,환자의 활동력 등을 고려하여 치료 방법을 결정하여야 할것으로 사료된다.EX>46N으로, 슬개건-티타늄 간섭나사군이평균 1067.4$\pm$145N에서평균 601.8$\pm$134N으로, 슬개건-생체흡수성간섭나사군이평균 987.1$\pm$168N에서588.7$\pm$124N으로각각40$\%$, 39$\%$, 50$\%$, 24$\%$, 44$\%$, 40$\%$가감소하였다. 결론: 수술후초기고정력은슬괵건을LA나사(R) 또는Semifix(R)로고정하는방법과슬개건을티타늄및생체흡수성간섭나사로고정하는방법등이우수하였으며, 슬괵건을생체흡수성간섭나사나Endobutton(R)으로 고정하는 방법 등은고정력이 상대적으로매우약함을 알수있었다. 최대인장력은단순인장검사로는이상의대퇴골측고정방법의고정력이초기부하를견뎌내는데충분하다고생각되었으나주기성부하실험후현저히감소되어충분한초기안정성을제공하지못함을알수있었다.를 나타내었다. 또한 3m깊이에서의 측방 선량분포에서 Spoiler의 거리변화(6, 10cm)는 심부선량의 변화에 영향을 주지 않는 것으로 확인할 수 있었다. 그리고 위의 실험측정치를 치료계획 시스템에 입력하여 선량분포를 확인한 결과 Spoiler를 사용하는 경우 OPEN에 비해 선량분포 영역을 표면으로 끌어 올릴 수 있으며 Bolus 보다 피부 보호효과는 어느 정도 유지가 되는 것을 보여주었다. 4.결론 이와 같이 Spoiler는 Bolus와 비교하여 6MV 광자선의 build up 영역을 표면으로 증가시키는 동시에 Skin Sparing(피부보호)효과를 유지할 수 있으며 두경부암의 치료에서 Spoiler의 사용이 가능한 조건으로는 조사면이

  • The present study was carried out to develop the better measures for safety of open heart surgery under extracorporeal circulation (ECC) with Heart-Lung-Machine by preventing changes in the concentrations of serum electrolytes during and after ECC. For this purpose, the cocentrations of serum electrolytes were measured before, during, and after ECC in 21 patients with congenital and acquired heart diseases who received open heart surger, - under ECC using Heart-Lung-Machine. Also considered was the development of safety measured by which changes in serum electrolyte concentrations were prevented during and after open heart surgery under ECC. The mean values for serum sodium levels were observed to be ; $13.14{\pm}0.47$mEq./L. for the samples obtained before ECC. $139.59{\pm}0.68$mEq./L. for the samples obtained 10 minutes after ECC and $138.0{\pm}0.68$mEq./L. for the samples obt"ined 24 hours after ECC. These results indicate that serum sodium concentrations were \\'ithin normal range during and until 24 hours after ECC. 2) The concentrations of serum chloride were found to be $105.38{\pm}0.70$105.38$\pm$0. 70 mEq./L. for the samples collected before ECC, $105.07{\pm}1.01$mEq./L. for the Simples collected 24 minutes aiter ECC and $101.95{\pm}1.09$mEq./L. for the samples collectect 24 hours afte ECC. As was tile case with serum sodium levels, no significant changes were observed in serum chloride levels during and 24 hours after ECC. 3)With proper provisions of potassium chloride solution during ECC, the concentrations of serum potassium were found to be $4.22{\pm}0.06$mEq./L. for the samples removed before EeC, $4.06{\pm}0.14$mEq./L. for the samples removed 10 minutes after ECC and $4.39{\pm}0.07$ mEq./L. for the samples removed 24 hours after ECC. 4)The concentrations of serum calcium were also maintained within normal during and after ECC; $9.15{\pm}0.14$mg/dl for the serum collected before ECC, $8.36{\pm}0.21$mg/dI for the serum collected 10 minutes after ECC and $8.47{\pm}0.14$mg/dl 21 hours after ECC. The maintenance of serum calcium level within normal throughout ECC was achieved by parenteral administrations of calcium gluconate as frequent as required. 5) As were the cases with serum potassium and calcium, the concentrations of plasma bicarbonate was regulated within normal range during and after ECC, only when sodium bicarbonate solution was admini"tered parenterally as it was required; $23.7{\pm}0.50$mEq./L. for the serum collected before ECC. $22.33{\pm}1.09$mEq.lL. for the serum collected 10 minutes after ECC and $25.3{\pm}0.96$mEq./L. for the serum collected 24 hours after ECC. The above results indicate tha t during and after ECC serum sodium and chloride levels remined unchanged without any provision of normal saline, while serum potassium, calcium, and bicarbonate concentrations were kept within normal limits only when these ealectrolytes were administered through parenteral routes. With these results it can be concluded that serum potassium, calcium, and bicarbonate levels should be determined as often as possible during and after ECC and that in order to maintain serum electrolyte levels within normal these electrolytes in the forms of potassium chloride, calcium gluconate, and sodium bicarbonate shou'd be given parenterally as they were found to be required.

  • As a part of epidemiologic investigation of tsutsugamushi disease, the wild rodents which were captured in Gyeongnam area were diagnosed with indirect immunofluorescent antibody assay (IFA) and Polymerase Chain Reaction (PCR) to find if they have an antibody against Orientia tsutsugamushi. The conclusion was drawn as followings. (1) The captured 58 wild rodents showed that the subspecies distribution of Apodemus agrarius was 86.2%, Microtus fortis was 8.6% and Crocidura lasiura was 5.2%. (2) The antibody positive rate of O. tsutsugamushi Gilliam, Karp, Karto and Boryong by IFA method was 32.0% in Apodemus agrarius among 50 wild rodents and 40.0% in Microtus fortis among 5 wild rodents, respectively. It was negative in the case of all the 3 Crocidura lasiura. (3) The antibody titers on Apodemus agrarius, Microtus fortis and Crocidura lasiura against Gilliam, Karp, Karto and Boryong were measured between 1:20 and 1:640. The antibody titer against each antigen was in the order Boryong>Gilliam>Karp. (4) O. tsutsugamushi was detected from the blood, spleen and kidney from the artificially infected mice by IFA and PCR. IFA showed the positive response between 3 and 18 days after inoculation. On the other hand, positive response was found from all the samples by PCR. (5) From PCR of the genomic DNA extracted from the blood, spleen and kidney samples of the captured wild rodents, Boryong-specific amplification product with size of 210 bp, which is particular in Boryong, was detected from spleen and kidney samples, but not detected in the blood. (6) Boryong-specific amplification product was detected from spleen and kidney samples which were obtained at 3, 6, 12, 18 and 24 days after the infection with Boryong. But, it wasn't detected from the uninfected samples. (7) From PCR of spleen and kidney samples of the captured wild rodents, it was found that positive rate of O. tsutsugamushi in Apodemus agrarius and Microtus fortis were 25.0% (4/16) and 20.0% (1/5), respectively. From the above results, it can be concluded that Apodemus agrarius resided in Gyeongnam area carried O. tsutsugamushi and PCR method might be a simple, precise, rapid and useful diagnostic tool than IFA for the diagnosis of O. tsutsugamushi.

  • 당뇨병 환자에서 $^{99m}Tc-colloid$ labeled scrambled egg와 hamberger를 이용한 고형식의 위배출 양상의 변화를 동위원소를 이용하여 고찰한 결과 당뇨병성 신경증의 정도, 특히 자율신경계 침습 유무, 이환기간 및 망막증의 정도와 관련이 있었고 혈당농도 및 조절상태와는 무관한 것으로 나타나 당뇨병 환자에서 신경장애가 심할수록 이환기간이 길수록 위장운동 장애가 심한 것을 나타내있다. 당뇨병성 위마비증도 자율신경계 침습이 있는 경우에 잘 발생하였고 Cisapride는 당뇨병 환자의 위 배출시간 및 위저류율을 호전시켰다. $^{99m}Tc-colloid$ labeled scrambled egg와 hamberger를 이용한 고형식의 핵의학적 정사 방법은 barium을 이용한 방사선학적 청사보다 정량화하기 쉽고 생리 식염수 부하검사보다 비침습적이며 당뇨병 환자의 실재 일회 식사량과 비슷한 500kCal의 열량으로 임상상을 잘 반영한다고 사료된다.

  • 교대작업이 근로자의 육체적, 정신적 및 사회적 건강에 미치는 영향을 조사하고자 1993년 5월 한 달간 경상남도 울산시 소재 모 자동차 공장 생산직 근로자 659명(교대작업자 : 544, 주간작업자 : 115)을 대상으로 설문조사 및 면접조사를 실시하였다. 조사시점에서 현재 교대작업을 하고 있으며 자신의 근무기간 중 80% 이상을 교대작업에 참여한 근로자를 지속적인 교대작업자로 간주하였으며, 조사 당시 교대작업에 참여하고 있지 않고 과거에도 교대 작업에 참여한 경험이 전혀 없었던 근로자룰 주간작업자로 하였다. 교대작업군과 대조군의 일반적인 특성 및 작업과 관련된 특성은 자기기입식 설문지를 이용하여 조사하였으며, 교대작업에 관련된 내용은 면접을 통한 자기기입식 설문지를 이용하여 조사하였다. 근로자의 수면양상과 식사형태에 관한 설문은 National Institute for Occupational Safety and Health에서 개발된 항목을 이용하여 조사하였으며, 위장관계질환의 자각증상에 관하여서도 자기기입식 설문지를 이용하여 조사하였다. 근로자의 일반적인 안녕 상태와 장해는 미국의 Health and Nutrition Examination Survey에서 개발된 자기기입식 설문인 General Well-Being Schedule(GWB)에 의해 측정되었다. 교대작업자에서 자신이 원하는 수면시간보다 1시간 이상 수면이 모자란다고 호소한 근로자가 56.8%로 주간작업군의 50.0%보다 높았으며, 수면 중 2회 이상 잠을 깨는 근로자의 비율, 잠에서 깨었다 다시 잠들기가 힘들다고 호소한 근로자의 비율, 일주일에 2일 이상 작업 중 피곤하거나 졸리다고 호소한 근로자의 비율, 일주일에 2일 이상 작업이 끝난 후에도 피곤하거나 졸리다고 호소한 근로자의 비율은 주간 작업자보다 교대작업자에서 현저하게 높았으며(p<0.01), 교대작업자에서 자고 일어난 후에도 피로감을 호소하는 율도 교대작업군에서 53.1%로 주간작업자의 40.0%보다 높았다(p<0.05). 수면의 형태를 보면 교대작업자에서는 각 교대작업 때마다 다른 형태의 수면을 취하는 근로자가 35.9%로 가장 많은 비율을 차지하였으며, 잠을 잘 못 잔다고 호소하는 근로자도 12.3%로 주간작업자의 6.1%보다 훨씬 많은 비율을 차지하였다. 잠을 자기 위해 약물을 상습적으로 복용하는 근로자도 주간작업자에서 1.7%, 교대작업자에서 2.8%를 차지하였다. 교대작업자들과 주간작업자는 다른 형태의 식사형태를 보였으나 유의한 차이는 없었으며, 식욕은 주간작업자의 13.0%에서 아주 좋다라고 응답한 반면 교대작업자에서는 6.6%만이 식욕이 아주 좋다라고 응답하였으며, 식욕이 매우 나쁘다라고 응답한 비율도 5.0%로 주간작업자의 2.5%보다 높았다. 교대작업자와 주간작업자의 위장관계 자각증상 호소율은 교대작업군에서 높았으며(p<0.01), 배변습관의 변화와 체중감소 호소율도 교대작업자에서 주간작업자에 비해 유의하게 높았다(p<0.05). 근로자의 일반적인 안녕 상태와 장해는 HANES I에서 개발된 General Well-Being Schedule(GWB)에 의해 측정되었는데 불안척도, 우울척도, positive well-being척도, 활력척도에서는 교대작업군에서 통계적으로 유의하게 낮았으며(p<0.05). 자기제어력척도, 일반건강척도도 교대 작업자에서 낮았으나 유의한 수준은 아니었다. 이상의 결과를 종합해 볼 때, 교대작업자에서 생체리듬의 부조화로 인한 수면, 식사, 위장관계장해 등의 일련의 자각증상에 대한 호소율이 주간작업자에 비해 전반적으로 높았으며, 일반적인 건강 장해 호소율도 교대작업자에서 높았다.
